' METAL CONTAINER.

Application filed Aiigust 9, 924. Seria1 No. 73 1,229. i v

In the construction of metal containers of. the type having a removable top or closure,

such as are finding a more or less extensive field of use in connection with the paint trade, for example, the prevailing construc tion. utilizes a body having an integrally formed folded flange extending inwardly adjacent one end thereof, the coverfitting closely in said end and havinga peripheral flange with its lower face substantially parallel to the upper face of said firstnamed flange. However, such folded flange on the container body 1s sub ected to considerable downward pressure when the cover seated, with the result that the flange is not infrequently bent from its normal horizontally PIOJQCillDg pos tion so that an imperfect seal is secured.

One object, accordingly, of the present invention is the provision ofa reinforced or rather strengthened form of suchflange in a container of the type in question. 'A further object is the incorporation of a pro tecting wire bead in the end of the container body above such flange, whereby it is rendered'unnecessaryto form such body with outwardly projecting beads below the can,

this being a more or less expensive operation and resulting at the same timeinthe formation of an annular groove in the inner *sur-' face of the can body.

To the accomplishment of the foregoing and related ends, the invent-ion, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and thefollowing description setting forth in detail certain mechanism embodying the invention,

such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invei'ltion may be used.

In said annexed drawing Fig. 1 is a top plan view of a container The body 1 of the containeris of cylindrical form, as usual, and aside from the:

ream-Baham referredltofl'as of special interest inaybe of any familiar construc tion both as to the form of the side seam, if

one be employed, and as to the manner in.

which the bottom is secured in place. i

'As shown in Figs'EZ and 3, the side wall;

of such bodyportion is. formed adjacent its upper open end with aninwardlydirected. 1

flange 2. This flange is formed byj folding the metal inwardly, the upper portion 2-? thereof lying substantially at right an glestoj;

such wall, i. e. in a substantially horizontal plane, while the lower portion is in close contact'withsuch upper portion for a'sliort' d stance only, theremalnder portion 2 inchmng downwardly, and '.outwardly [to where the flange joins the body 1. The l horizontalportion 2 ofthe flange 2 constitutes a seatfor a gasket 3 which is shown as consistingof a. rubber tube collapsedor flattened. by the compressive action of the cover, as will bev presentlyexplained. It will be lunde'rstood,however, that dependmg upon conditions and the characterof the contents ofthe can, variouskinds of gaskets may be employed,0r forfthat matter-the cover may contact directly with the f seat 2.

As shown in Fig. 4,"the sideiwallffof the containeris initially formed with two series of cn'cumferentially spaced projections ,4!

former and alternating therewith, a, series and 5, the latter being smaller than thefj of slots'G being left between the adjacent] projections so as to provide against inter? ference therebetween. The projections 4 are bent outwardly around a circular. rein forcing wire 7 that held thereby closely against the upper edge of the containers side wall, as defined by the bottoms of the slots 6. However, as shown in Figs. '2 and 3, said reinforcingwire is located somewhat above the edgein question and thus above the edge of the top or closurejS'when the latter IS secured in place. V J

Such top or closure'is of general circular shape and is provided with an upturned per ripheral flange 9 having an external diameter slightly less than the internal diameter of the container above the flange 2., Contiguous with such upturnedor vertical flange 9 such top or closure is provided with a horizontal flange 10 in the form of construction shownin Figs. 2 and 3, such horizontal flange lying below the main body of fication in that the lower portion 2 of the.

inwardly directed flange 2 on the can body slopes downwardly and outwardly from the inner edge of such flange instead of from a point intermediate of snch inner edge and the outer edge of the horizontal portion 24,

Prior to the insertion of the top or cover 8 in place in the open end of the container body, the projections 5 thereon extend upwardly, as indicated in dotted outline in Figs. 3and 5, but after insertion of such cover these projections are bent inwardly .anddownwardly so as to force such cover downwardly and thereby compress the gasket 3 between the horizontal portion 2 of the flange 2 and the horizontal flange 10 of the cover 8 or else'the body of the cover 8 Where the flange in question is continuous with such body.

As a result of the formation of the flange 2 with the lower portion 2" 01 2, as the case may be, inclining inwardly from the can body to the inner edge of such flange or to a point sligthly removed therefrom, the horizontal portion 2 of such flange is braced or supported as by a continuous bracket. Accordingly, such horizontal portion 2 will be maintained in position under much more severe compression strainswhen thefcov er 8 is forced into place than ifthe flange 2 were of familiar folded form. The reinforcingvwir'ej, as need not be explained in detail, provides an entirely adequate protection for the end of the. can and prevents injury to such end and distortion of the seat I 2 on account of externally applied blows or'bump s Other modes of applying the principle of my invention maybe employed instead of the one explained, change being made as regards the mechanism herein disclosed. provided the means stated by any of the following claims orthe equivalent of such stated means be employed.

I therefore particularly point out and dis tinctly claim as my inventionz 1. In a metal container, the combination of a body portion provided adjacent its open end with an inwardly directed flange formed by folding the material of said body 1n war :lly,.the upper. portion of said flange lying at substantially right angles to said body portion to form a seat and the lower portion of said flange lying in close contact with such upper portion for a short distance adjacent its inner edge and then inclining downwardly and outwardly whereby to form an intermediate buttressfor the seat, and a cover adapted to fit within such end of the container body and having a complementary seat. V i

2. In a metal container, the combination of a body portion provided adjacent its open end with an inwardly directed flange formed by folding the material of said body inwardly, the upper portion of said flange lying at substantially right angles to said body portion to form a seat and the lower portion of said flange lying in close contact with such upper portion for a short distance adjacent its inner edge and then inclining downwardly and outwardly whereby to form an intermediatebuttress for theseat, a cover adapted to fit within such-end of a container body and having a complementary seat, and spaced projections on said body end adapted to secure, said cover. 7

3. In a metal container, the combination of a, body portion provided adjacent its open end with an inwardly directed flange formed. by folding the material of said body inwardly, the upper portion of said flange lying at substantially rightangles to said body portion to form a seat with an angular buttress intermediately below, a' circular wire reinforcing said body-end, the latter being formed; with integral, circumferentially spaced pro ections on said body-end bent outwardly and around said, w re tohold thesame in place, a cover adapted to fit within such end and formed with a complementary seat, and means for securing said cover in place, said means comprising integral, circumferentially spaced projections on said body-end lying between said firstnamed projections and adapted i'OdJQ: bent inwardly into engagement with said cover.

Sig'ned'by me this 6th day of August, 1924.
